WAGON-COUPLING.

SPECIFICATION forming part of Letters Patent No. 636,944, datedNovember'- 14, 1899. Application filed June 13, 1898. Serial No.683,325. (No model.)

Improvement in Wagon-Couplings, of which the following is aspecification.

My invention pertains to the king bolt or pin coupling in the frontrunning-gear of an ordinary road wagon. Its object is to so protect theparts of the wagon through which the pin passes as to prevent thepin-holes being enlarged from wear and the parts being weakened thereby.

The novelty of my improvement is illustrated by the accompanyingdrawings, in which' Figure 1 is a top View of the frontrunninggear of awagon. Fig. 2 is a front or rear view of the front axle, sand-board, andbolster of a wagon. Fig. 3 represents a top view of the front end of thereach or coupling-pole and an enlarged perspective view of the same.Fig. 4 is an enlarged perspective of the me tallic plates and tubularlinings for the hole in the bolster and sand-board, and Fig. 5 is aperspective view of the plates and tubular lining for the hole in theaxle of the wagon.

Similar letters refer to similar parts in the several views.

In the ordinary road-wagon the bolster, sand-board, and axle are made ofwood, and

- the king bolt or pin is put in a hole bored through them without beingprotected or reinforced in any way to prevent wear. The

force of the reach or coupling-pole on this pin in time so wears andenlarges the pin-hole'as to greatly weaken these parts of the wagon, andthus cause it to break down. This is es pecially true in a rough ormountainous country, where the strain and wear on these parts of a wagonare Very great. My improvement is designed to so reinforce, protect, andstrengthen these parts of the wagon as to prevent the king-pin holebeing enlarged, and thus obviate breakage on account of the parts beingweakened from wear. I accomplish this result by means of mynewly-devised improvements, illustrated in the accompanying drawings.

The front axle is represented at A, and B is the front bolster; O, thesand-board.

D is the reach. The front hounds are indicated by E, and the king-boltby K.

The top of the bolster is protected by means of a thin metal plate a,extending from end to end. In the center is a socket-like depression e,in the bottom of which is fixed a tubular extension (1, that fits neatlyin the king-pin hole of the bolster. On the under side of the bolster isa pivotal sliding plate b, with a central hole large enough to receivethe lower end of the tube 01. The plates are firmly anchored tothebolster by means-of rivet-bolts through the holes'f. The socket 6allows the head of the pin to rest flush with the top of the bolster.These plates, with the connecting tubular lining fitted in the hole,protect the bolster from wear and greatly add to its strength. The holein the sand= board is similarly protected by means of plates g and i anda tubular connection h, lining theking-pin hole. Likewise the axletreeis protected by means of the plates j and Z and the connecting tubularlining k. The king-pin is thus confined within the metal linings and hasno contact with the wooden members of the wagon, and the parts are notworn nor weakened thereby.

The reach is protected by fitting the front end in a metallic box-likecase we, having a tubular openingp fixed through its center, thusforming a metal-lined hole for the kingpin. A top piece to is fixed inplace with rivet-bolts, thus not only forming a protection to the hole,but also to the sides of the reach.

With these improvements added to a wagon it will be so protected fromwear and tear that the parts will not be worn nor weakened sooner thanother parts of the wagon.

Having thus described my invention, What between the plates of themiddle set and receiving the metallic tube thereof, the axle lyingbetween the plates of the lowermost set and receiving the metallic tubethereof, and the king bolt or pin passing through the metallic tubes ofthe three sets of plates which register one with the other, the head ofsaid bolt lying within the socket of the top plate of the uppermost setof plates, substantially as described.

2. The combination with the bolster, the sand-board, and the axle, eachformed with a king bolt hole and provided with a top and bottom plateconnected by a metal tube, the tubes of the several plates registeringwith
